6.3 Primary Scan Head Connector
The 25-pin D-SUB connector for the scan head is
compatible with most scan heads which use the
XY2-100 standard. The pin out is shown in
figure 25
on page 54 .
Control Signals
Data channels CHAN1 through CHAN3 transmit
control values to the scan head. The SYNC and CLOCK
channels transmit synchronization and clock signals
to the scan system.
The CHAN3 channel is optionally provided for
controlling a third axis in a 3-axis system.
Please contact SCANLAB for further information (also
see
chapter 7 "Options", page 57 ).
For additional information, please contact SCANLAB.
Status Signals
The STATUS channel receives XY2-100 standard
compliant status signals returned by the scan system.
Consult your scan system’s operating manual to
determine which status signals are generated by your
scan system and how they can be applied for moni-
toring purposes.
6.4 Secondary Scan Head
Connector (Optional)
The 26-pin connector “2. SCANHEAD” on the RTC
®
4
board is designed for connecting a second scan head
in a double scan head configuration. The pin out of
this connector is shown in
figure 26 on page 54 .
The signals on this connector are optional and must
be enabled by SCANLAB. Please contact SCANLAB for
further information. Also see
chapter 7 "Options",
page 57 .
SCANLAB recommends using an additional slot cover
for connecting the second scan head. A suitable slot
cover with a 25-pin D-SUB connector – with a pin out
as shown in
figure 25 on page 54 – is available from
SCANLAB.
